The test couplings system guarantees at any time, place and condition, the immediate and manual verification of the pressure inside the system, without interrupting its activity up to pressures of 630 bar.
The range includes different threads starting from 1/8 BSPP (1/8G) up to 1/2 BSPP (1/2 G). The external body is made of high-strength steel and protected from oxidation by a zinc plating.
